"4 BRAKE FOR A SNOW SKI SUMMARY The invention relates to an improvement in a brake for a snow ski which mounts on the top surface of a ski. It is an object of the invention to provide a brake for a ski which has ground engaging spikes movable from a raised postion above the running surface of a ski to a locked position with the spikes extended below the running surface of the ski to aid in climbing snow covered slopes or prevent slipping thereon.
In the drawings forming part of this application:
FIG. 1 is a top plan view of a ski brake embodying the invention.
FIG. 2 is a side elevational view thereof.
FIG. 3 is a rear end view on the line 3-3 of FIG. 2.
FIG. 4 is a front end view on the line 44 of FIG. 2.
FIG. 5 is a sectional view on the line 5-5 of FIG. 3.
FIG. 6 is a view similar to FIG. 5 but with the brake in a raised inoperative position.
FIG. 7 is a perspective view of the central mount and actuator removed from the device.
FIG. 8 is a perspective view of a further embodiment of a central mount and actuator.
Referring to the drawings in detail, the ski brake A includes the central mount 10 which includes the spaced side walls 12 and 14 connected at the top by the top wall 16. The lower ends of the side walls 12 and 14 are formed with the right angular flanges 18 and 20, respectively, formed with the screw-receiving holes 22 used to secure the same to the base portion 70 by means of rivets or screws 23 or the like. The walls 12 and 14 are also formed with the aligned holes 24 and 26. Further provided is the saddle 28 which includes the top portion 30 from the side edges of which depend the spaced side flanges 32 and 34. The lower edge 36 of the saddle side walls tapers from the wider end at the front to the narrower portion at the rear. The top wall 30 is formed with the slot 38 and the socket 40. the saddle 28 is pivotally mounted on the central mount 10 by means of the pin 42 extended through holes 44 formed in each of the side flanges 32 and 34. Each of the side flanges 32 and 34 is formed with a slot 42. The side walls 12 and 14 are each cut out with the recess 44, and the top wall foreshortened with respect to the side walls as at 46 which coincides with the recesses 44 whereby the saddle may be pivoted downwardly on the mount 10 as hereinafter referred to.
The numeral 48 designates a block which is secured between the flanges 12 and 14 of the mount 10 by means of the rivets 50 and 52 through the holes 24 and 26 of the flanges slidably mounted on the top of the block 48 and within the top wall 16 and sidewalls is the latch 54 which has the Pin 56 extended through a hole in the latch with the extended ends of the pin 56 extended through the slots 42 formed in the side walls 32 and 34 of the saddle 28. The latch is formed with the forward bevelled end 57.
The block 48 has the extension 58 formed thereon positioned so as to form the recess 60. Secured at its lower end in the extension 58 is the rod 62 with the upper end of the rod extended through the slot 38 of the top wall 30 of the saddle 28. Mounted on the rod 62 is the coil spring 64 which abuts between the top wall 30 and the extension 58 of the block 48, and which normally urges the saddle 28 in the horizontal position as shown in FIGS. 1-5. It will be seen that the upper end of the pin 62 acts as a stop for the rear end of the slot 38 thereby holding the saddle 28 in the position of FIG. 5 and when the saddle is released as in FIG. 6.
The numeral 68 designates a base member which includes the flat portion 70 formed on each side edge with the upstanding side bracket portions 72 and 74, and mounted on the bracket portions 72 and 74 is the cross shaft 76. Mounted on and extending outwardly from the top portions of the side brackets are the stop lugs 78 and 80. It will be seen that the block 48 is positioned on the base flat portion 70 and the central mount 10 is also on top of the base portion 70. The base 68 is secured to the ski by the screws 71.
Further provided is the yoke 82 which includes the triangular shaped side member 84 and 86 connected at the front by the vertical cross piece 88. Extending from the front cross piece and at a right angle thereto is the lip 90 formed with the depression 92. The rear ends of the side members 84 and 86 are pivotally mounted on the ends of the shaft 76. Secured to the front side edges of the side members 84 and 86 are the spikes 94 and 96, respectively, the length of which is such that the same extend to a point below the bottom surface of the ski when the device A is secured upon the top surface of the ski as in the FIGS. of the drawings.
The cross piece 88 is formed with the slot 98 where it joins the lip 90 providing the shoulder 100. The numeral 102 designates a spring which includes the first long leg 104 which at the outer free end extends through and is anchored in the hole 106 formed in the cross piece 88. The leg 104 is wound around the shaft 76 as at 108 which terminates in the first short leg 110 which terminates in the cross portion 112. The cross portion 112 is positioned in the recess 60 and upon the flat base 70. The cross portion also terminates in the second short leg 114 which terminates in the portion 116 wound around the shaft- 76 which terminates in the second long leg 1 18 the outer "free end of which extends through and is anchored in the hole 120 formed in the cross piece 88. The spring normally urges the yoke 82 upwardly and holds the same in the position shown in FIG. 6 with the spikes in inoperative position, and the top edges of the side members 84 and 86 engage the stops 78 and 80 which limit the extent of the upward movement of the yoke 82.
OPERATION The ski brake A operates in the following manner. In FIG. 5 the spikes are shown in lowered and locked operative position. To raise the yoke and spikes thereon into inoperative position as in FIG. 6, whereby the spikes are at a point above the bottom surface of the ski, a rigid instrument in the form of the ski pole end S is positioned in the socket 40 and pushed downwardly. As that is done the saddle is pivoted downwardly on the pin 42 which draws the latch 54 backwardly upon the block 48 by means of the pin 56 in the slots 42 of the saddle against the spring 64. As the saddle is pivoted downwardly about the pin 42 the forward edge of the slot 42 bears against and draws the pin 56 and latch thereon rearwardly. The slot 42 allows movement relative to the pin 42 for the saddle pivots about the axis of the pin 42. With the latch 54 withdrawn from the slot 98, the yoke 82 and spikes thereon is raised to the inoperative position of FIG. 6. With the pole tip S removed the latch 48 and the saddle 28 return to the position of FIG. 5, but the yoke 82 remains in the up position of FIG. 6 due to the spring 102.
To place the device in operative braking position a pole tip such as S is pushed upon the depression 92 whereby the inner or rear surface of the cross front piece strikes the bevel portion 57 of the latch 54 thereby pushing it backwardly and with further movement of the piece 88 the latch reaches the slot 98 and enters the same and engages the shoulder edge 100 of the slot. With the latch so engaged in the slot the brake is locked in a down position as in FIG. 5.
FIG. 8 illustrates a further embodiment of the central mount 10 as 10a and the actuator 28 as 28a. The central mount 10a includes the block 11 formed with the slot 13 in which the latch 54 is slidably mounted. The central mount 10a is also formed with the holes 24a and 26a. The actuator 28a is identical to the actuator 28.
